## What reviewers found

### Dolphin (Maytronics) Cayman

- The Pool Nerd: Rated it best value; praised the weekly timer, corded consistency and top load MaxBin, noted it lacks an anti tangle swivel. Affiliate site with links to Dolphin dealers. [Source](https://www.thepoolnerd.com/dolphin-cayman-review)

### Dolphin Nautilus CC Supreme

- PCWorld: Tested for about 10 days. Collected roughly 90% of test debris in about an hour and regularly 95% or more on the 3.5 h cycle; saw no difference between regular and ultra clean modes. Cleanup of six filter pieces was tedious, the app was slow, and the 25 lb robot was hard to lift out. [Source](https://pcworld.com/article/3134641/maytronics-dolphin-nautilus-cc-supreme-review.html)
- The Pool Nerd: Rated it Pool Nerd Disapproved on value, not cleaning: strong floor, wall and waterline cleaning with dual scrub brushes, but only a 1 year warranty and standard cartridge filters on an older platform.
